Abstract: A torque management system and method is described by which the torque provided by an engine can be controlled based on a mass of the vehicle and, if available, instantaneous and/or predictive slope information. Also, in some modes of operation, torque can be controlled based on speed limit information for upcoming road segments to be traveled by a vehicle. In addition to controlling the maximum allowable torque, optionally the minimum allowable torque can also be controlled to prevent inadvertent decelerations of the vehicle. A driver/operator can optionally override the torque control and the history of override requests can optionally be used to adjust overrides of the system. A plurality of torque control approach sub-methods can be made available with the appropriate sub-mode being selected depending, for example, upon the extent of the available information.

Abstract: A diesel exhaust treatment system comprises a housing provided with a drive shaft passageway. The driveshaft of a land vehicle passes through the drive shaft passageway when the drive shaft and diesel exhaust treatment apparatus are incorporated into a vehicle. The housing can be coupled to frame rails of the vehicle with at least a portion of the housing being positioned between vertical planes containing the outer surface of the frame rails. In one specific embodiment at least a portion of the housing is positioned between the frame rails. The housing can comprise a plurality of housing sections, such as upper and lower housing sections which each define a portion of the drive shaft passageway. In addition, the upper housing section can be shorter than the lower housing section.

Abstract: In a drive train for a motor vehicle having at least first and second drive axles each provided with two drive wheels for moving the motor vehicle, wherein the drive train comprises a first drive unit connected to the first drive axle and a second drive unit connected to the second drive unit for driving the wheels of the drive axles or, respectively, being driven thereby, the wheels of the first and second drive axles are operable independently of each other and clutch elements are arranged in the drive train between the wheels of the second axle and the second drive unit for mechanically disconnecting the second drive unit and the wheels of the second drive axle.
